Variation of the distance between long HLOS and short HLOS subpopulation prototypes (y-axis) generated by different code-level similarity formula with respect to the size of the subpopulation prototype(x-axis). A longer distance indicates that prototypes can be separated more distinctly. a The comparison results of the younger population (age ≤ 50 years). b The comparison results of the elder population (age ≥ 50 years)
